摘要

电能计量是电力企业与用户进行电能核算的数据基础，其计量准确性与企业和用户的利益息息相关。错接线检查是保证电能计量装置正确计量的重要环节。针对三相三线电能计量装置的接线特点，分析电能表测量数据与不同接线形式之间的关系，将测量电流与测量电压间夹角取值范围与接线形式的对应关系归纳成表格，实现了对三相三线电能表接线形式的快速判断。在此基础上，将三相三线电能表错接线的理论判断方法转化为算法模型，设计出基于电能表测量数据自动接线判断系统软件。该系统以远程自动判别取代人工周期性现场巡检，在大幅提高错接线判断效率的同时，也极大地节省了人力物力。

Abstract

As the data base of electric energy accounting between electric power enterprises and users

the accuracy of electric energy measurement is closely related to the interests of enterprises and users. The wrong wiring check is an important link to ensure the correct measurement of electric energy metering device. The wiring characteristics of three-phase three-wire energy metering devices were analyzed

and the relationship between the meter's measurement data and different wiring configurations was examined. The correspondence between the range of phase angles between measured current and voltage and the wiring configurations was summarized into a table

enabling rapid identification of wiring modes in three-phase three-wire energy meters. Based on this

the theoretical method for detecting incorrect wiring was transformed into an algorithmic model

and an automated wiring judgment system software was designed using the meter's measurement data. This system replaced manual periodic on-site inspections with remote automatic detection

significantly improving the efficiency of incorrect wiring identification while greatly reducing labor and material costs.
